IMPROVEMENT IN MACHINES FOR BARBING FENCE-WIRE.

Specification forming part of Letters Patent No. 217,673, dated July 22,1879; application filed June 22, 1878.

To all whom it may concern:

Be it known that I, GEORGE O. BAKER, of Des Moines, in the county ofPolk and State of Iowa, have invented a Machine for Barbin g Fence-Wire,of which the following is a specification.

The object of my invention is to furnish a light portable machine thatis adapted to be operated by hand and foot power to automatically movefence-wire and fix barbs upon the same at regular intervals of space andin such a manner that the projecting barbs will be crowded upon thecoils of the same barb-pieces to lock the complete barbs rigidly uponthe fence-wire.

It consists, first, in combining barb-forming mechanism and wire-movingmechanism, by means of a bench and two treadles, in such a manner thatthe downward motion of one treadle will operate the barb-forming deviceby means of a rack and pinion,and at the same time elevate the secondtreadle and hold inoperative the reels, while the downward motion of thesecond treadle will actuate the reels and move the fence-wire and at thesame time elevate the first treadle and the rack into the positionsrequired to be in readiness to again operate the barb-forming device;sec- 0nd, in the manner of forming and operating lateral moving jawsthat close to hold the fence-wire, and open to allow the barbs to passafter they are fixed on the wire; third, in the manner of forming anadjustable barb-former and. combining it with the sliding jaws in such away as to cause it to crowd the projecting barb-points upon thebarb-coils, to prevent them from uncoiling, all as hereinafter fully setforth.

Figure l of my drawings is a perspective view of my complete machine.Fig. 2 is a sectional View showing the construction and operation of thelateral-moving jaws. Fig. 3

is a longitudinal section of the rotating head that wraps the barbs uponthe fence-wire, and also an end view of one of the extensions of thesliding jaws that hold the short ends of the barb-pieces while theirlong ends are being wrapped in parallel coils upon the fencewire bymeans of the rotating head ortwister.

Fig. 4 is a sectional and top view, showing the construction of myadjustable and rotating head and shaft used to wrap the barb pieces uponthe fence-wire while the fence-wire and the ends of the barb-pieces arerigidly held by means of the sliding jaws. Fig. 5 is a perspective viewof my improved barb.

Jointly considered these figures illustrate the construction andoperation of my complete invention.

Similar letters of reference are used to denote like parts that appearin several figures. A represents a bench or stand, that may vary in sizeand material, as desired. B is a reel mounted in a vertical position onthe top and right end of the bench. O is a reel of corresponding sizemounted in horizontal position at the opposite end of the bench. D is atreadle pivoted to the bench in a horizontal position in such a manneras to extend from under the reel 0 to a point immediately under thebarb-forming mechanism. 0 is a crankarm pivoted to the axle of the reel0. g is a ratchet rigidly connected with the end of the same reel-axle.f is a pawl pivoted to the arm 6, to engage the ratchet g. his a rodconnecting the crank-arm c with the short arm of the lever or treadle D.I: is a spring-pawl extending from the bench to the ratchet g, toprevent any backward motion of the reel and wire.

a a is the metal frame and base of my barbforming mechanism, bolted uponthe top and central portion of the bench A. b is a rack that extends andmoves vertically through a suitable bearing formed in or attached to thebase a a. c is a rod attached to the lower end of the rack. It extendsdownward and is flexibly connected with a treadle, D, that is pivoted tothe bench in such a manner as to bring the two treadles at right anglesto each other and their free ends contiguous to each other.

I I are:lateral-moving jaws sliding in suit- I able bearings J, thatrise vertically from the base-plates a a. Each jaw hasa triangularshapedopening, is, in its under side, which terminates at its top in the formof a socket.

l l are levers pivoted to suitable bearers or fulcrums that extend fromthe bench or base. The top endsof these levers l are fitted into thesockets formed in the central parts of the I shaft U.

sliding jaws I, and their lower ends connected with a pivoted handle, m,by means of lazytong levers n 0, or other suitable operative devices.

The jaws I have extensions 1" formed on or attached to their inner endsto fit against a fencewire and to hold the wire rigidly while barbpiecesare being coiled upon the fence-wire by means of the barb-formin gmechanism that is cooperated with the jaws, as shown by Fig.

3; and the extensions T have openings in their corners to form shouldersthat will engage and hold rigidly the ends of the barb-pieces while theyare being coiled upon the fencewn'e.

s is the removable head of my barb-former. It is preferably formed intwo uniform parts, and has a screw-shank, t, that enters the tubularshaft U. The head thus formed and applied is bifurcated at its free endto allow the wire barb-pieces to pass through and to engage them when itrotates, to wrap the projecting portions of the barb-pieces around thefence-wire while the barb-pieces and the wire are held by the gripingends 1' r of the sliding jaws I. i

The combined head 8 t and shaft U has a bore through its longitudinalaxis, through which the fence-wire is passed from the reel B to the reel0. w is an adjustable collar on the This collar abuts against theshaftbearing 00. It carries a set-screw, by means of which it can bereadily fixed to the shaft. By adjusting the collar the shaft can bemoved longitudinally as required to adjust the head 8 relative to thejaws I. Byfthis means the head can be kept close to the jaws, and thecoils of the barb crowded close together, and the wearing of partscompensated for by adjustment. I

y is a pinion fixed on the shaft U at the opposite end of its head 8 toengage the rack I).

In the practical operation of my invention a spool of wire is placed onthe reel B, and the free end of the wire passed through the tubularshaftU and fastened to a spool on the reel 0. Two pointed wirebarb-pieces, 22, are then placed in position over the fence-wire, asshown in Fig. 3, to rest against shoulders formed in the ends of thejaw-extensions r, and to extend through the opening of the rotating head8. A block, 4', fixed under the head 8, has a shoulder, and consequentlytwo level surfaces and planes at two different points of elevation toform rests for the barb-pieces, as shown in Fig. 2, and to regulate thesetting of the barbpieces relative to the fence-wire, upon which theyare to be wrapped in parallel and interlocking coils, to form arigidly-fixed fourpointed barb. When the barb-pieces are thus placed,treading upon the lever D will pull down the rack 12, and therebyactuate the pinion 3 and the shaft U, and rotate the head s, and causeit to wrap the barb-pieces upon the fence-wire in the manner illustratedby Fig.

4, and in such a Way that the projecti'ng'e'nd's 1 2 3 4 will be pressedupon and partly over lap the coils 5 6, to thereby form an interlocked.barb that cannot be uncoiled without first bending the points away fromthe coils. Press ing down the free end of thelever D after a barb isthus formed, the upward motion of itsopposite end will, by means of theratchet device e fg h, rotate the reel 0 and move the fencewire; andin'order to let the barb just formed pass the jaws I, which were closedby means of the handle m, the jaws are first opened by a reversemovement of that handle; and the same portion that pressed down thelever D, and thus moved the fence-wire, lifts the lever D by means of acord, 11", that connects the two treadles, and passes over a pulley, b,that is secured to the top edge of the bench A, and makes the machineready to form another barb on the fence-wire.

Fence-wire may be thus readily moved at regular intervals of time, andbarbs successively fixed thereon at regular intervals of space, asrequired, to produce barbed fencewire.

To dispense with the cord at and pulley I) I attach a coiled spring tothe rear portion of the lever D, and fasten it at its top end to theunder side of the bench A, so that in its normal position the springwill hold up the front end of the treadle, and always raise the sameafter the pressure that pulls it down is relaxed.

I claim- 1. In barb-forming machines, the combination of the reel B, thereel 0, the levers D and D, the cord and pulley a b, the crank e, pawland ratchet f g, and connecting-rod h, substantially as shown anddescribed, to operate in the manner set forth, for the purposesspecified.
